Vwhich will hold the seat yieldingly in raised position. A further object of the invention is to provide a spring hinge of this type with means for limiting the upward swinginmovement of the seat. he invention consists in the features of improvement hereinafter set forth, illustrated in the preferred form in the accompanying drawings andV more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a partial side elevation of a closet bowl and seat with the improved spring hinge applied thereto. Fig. 2 is a front view of the same, parts of the bowl being shown inv section on the .line 2 2 of Fig. l. Fig. 3 is a vertical rear elevation of the improved hinge. Fig. 4 is an enlarged plan view with the hinge structure shown in section. Figs. 5 and 6 are cross sections on the lines 5 5 and 6 6 of Fig. 4c. Fig. 7 is a view similar to Fig. 5 illustrating a modification.

'Ihe members of the improved hinge, which are securedl respectively to the closet bowl Aand the seat B, are provided Vwith overlapping end portions preferably in the form of pairs of ears 10 and 1l thnough which extends a connecting hinge pintle 12.

The hinge member having the ears 10 is also provided with a transverse portion 13 which connects the lower rear side portions of the ears 10 and is preferably cast integral therewith.` This hinge member, is adapted to be secured to the upper rear portion of the closet bowl and, for this purpose, is provided at its ends with integral seating flanges or feet 151 having rounded upper faces and horizontal lower faces which are arranged to engage the upper horizontal face of the flange a of the bowl A; The seating portions 14 are also provided" with integral depending bolts 15 which j extend through openings provided therefor in the bowl flange, and nuts, 16 and washers 17 upon the lower ends of the bolts, secure the hinge structure in position. It should be noted that the lower faces of the seating portions 14 are below the overlapping ends and other parts of the hinge members so that the latter are properly supported in posiltion above the upper face of the closet The other hinge member comprises a transverse portion 18 which connects the ears 11 and a Seatengaging flange 19, the portion 18 and flange 19 being preferably cast integral with the ears 11. In the form shown in Figs 1 to 6 inclusive the seating flange is tangentially disposed with reference to the ears 11 and is adapted to eX- tend beneath and be secured to the lower face of the seat B by screws extending through openings formed therein. Preferably, this flange is of considerable extent and the rear edge .of the seat is adapted to abut -avainst the ortion 18 of the hino'e member so that the seat is rigidly secured to the hinge structure.

In the construction shown, the ears 1l are arranged outside of the ears 10 and the outer portions are in the form. of truncated cones. One of the ears 11 is provided (see Fig. e) with a seat for the conical head 2O of the hinge pintle and the other is provided with a threaded socket to receive Vthe opposite threaded end of the pintle.

The hinge members are provided with cooperating stop portions for arresting the upward swlnginomovement of the seat. For this purpose the rear portions of the ears 10 are enlarged or extended radially to form stops 21 having forwardly facing radial faces which are arranged to coperate and engage the rear, radial edge face of the part 18 of the other hinge member. Preferably, these stop portions are arranged to arrest the upward swinging movement of the seat with the latter inclined forwardly and upwardly as indicated most clearly in Fig. 1. The parts are held in the position shown `by a spring 22 coiled about the pintle 12 and connected at its ends respectively to the hinge members.

In the preferred construction shown, the spring 22 is provided with inwardly projecting ends which detachably engage notches 23 formed in the inner ends of two Vcollars 24 and 25. Thesecollars are cylindrical and removably t upon the pintle 12 and within cylin drical openings in the ears 10, with the ends of ythcseat B of the spring 22 engaging the notches 2301i the inwardly projecting ends of the collars.

rlhe collar 25 is provided with an. enlarged outer end portion or flange 26 which is arranged between the ears l() and llat one projecting end of this stud is arranged to engage a seat formed in the adjacent edge of the part 1.8 of the seat-engaging hinge member. A stud 29 removably threaded into the other collar 24k is arranged to en.- gage the adjacent edge of the part 13 of the other" hinge member. In this way the spring is connected to the separate hinge members and normally holds thestop portions' 18 and 2l in engagement 'with the seat raised and preferably upwardly and forwardly inclined. rlhe tension of the spring may be radially adjusted by placing the stud 28 in any one of the radial holes or seats`27.

A. cylindrical barrel 30 is provided for inclosing vthe spring 22. This barrel is-of a length suiiicientto extend between the inner faces of the ears'lO. The oppositeends of the barrel are formed by two washersl that snugly fit within counter-bored endv portions of the body of the barrel and looselyfitupon the inner projecting ends of the collars `24 and 25. At one point, the barrel 30 is provided with an opening for the stud 29.

The improved structure may be readily tahenapart for repairs and the like without detaching the hinge members either from the closet seat or bowl. `Thus, by removing the studs 28 and 29 and the hinge pintle l2-the headed end of the latter is 'slotted to receive a screw driver-the seat and seatengaging hinge member can `be removed. The collars 24 and 25` can bc moved outwardly through the ears 10 and thus disengaged from the ends of the spring and spring barrel. The latter can then 'be slipped laterally from between' the ears l0. Thus, the hinge structure, while extremely strong and rigid,rcan be readily taken apart for repairsyrenewals or the like.

,Y The construction shown in Fig. 7 is similar to that shown in Figs. 1 'co5 except that instead of having a seat-engaging flange which is substantially radial with respectl'o NtheaXis of the hinge, it is provided with a seat-engagingV flan geV 32 which extends in circumferential direction with yreference to the hinge axis, andtog ether with ai'lange or stop portion 33 that projects, toward the Ihinge axis, forms the main body ofthe seat* engagingghinge member. vThe seat-,engagingflange v32 -abuts against the rear edge face and is preferably secured thereto by a pair of attaching bolts 34 fixed within the body ofthe seat andprojecting from the rearedge thereof. Nuts 35 threaded on the bolts are disposed beneath the flange Vor portion 33 and engage the outer faceof the` flange or portion 32 and rigidly connect the `seat tothe hinge member.' In this form, the lianges 32 andr33 are connected to the ears 11 by the integral end porv tions 36 and the stud 28 engages a lug 37 vvformedupon the hinge member at one end.

It is obvious that changes may be made in the detailsset forth without departure from the essentials of the invention as defined in the claims.
